For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and ... En savoir plus
Lithium ion battery safety problem has attracted the whole world’s attention essentially after the explosion of Samsung Note 7. This work mainly deals with the study of the generation, characteristics and prevention measures of the battery fire. Firstly, the heat generation rate of ... En savoir plus
This paper studies the application of laminate magnetoelectric (ME) material in displacement sensor. We studied the L-L block composite thanks to designed structure by coupling displacement signal with the displacement potential of ME composite. A nonlinear approximation is adapted to ...

Recently, the researchers usually use the hydrodynamic Drude model (HDM)to investigate the nonlocal optical response of metallic nanostructure. The advantage of the HDM is easy to implement numerical calculation for larger and more complex shaped nanoplasmonic structures. For the HDM, it ... En savoir plus
Microwave heating has many advantages over the traditional heating method, such as needing shorter time, saving more energy, and being easier to control. But there still are some problems.(1) Themal runaway still exists because the reflection and absorption of microwave by the reactants ... En savoir plus
Microwave heating is known for its efficiency and instantaneity. However, the non-uniformity of the microwave heating has limited the development of its application in industry. In order to solve this problem, a metal patch sticking to the turntable was proposed. During the heating ... En savoir plus
To overcome the uneven heating during the process of microwave heating of food inside microwave oven, a geometrical model based on domestic microwave oven with a cylindrical container composed of multi-materials(with two different kinds of materials, one half is glass and the other half ...

A patch antenna based on metamaterials of composite split-ring-resonators (CSRRs) and strip gaps is designed with COMSOL Multiphysics® software. The antenna is constructed by using CSRR structures in forms of circular rings on the patch and employing strip gaps on the ground plane. The ... En savoir plus
Two-generation superconducting coils carrying large current in alternating magnetic fields is very common in electrical applications such as HTS linear motor. So it is meaningful to study the characteristics of coated superconductors in the presence of travelling magnetic field. In this ... En savoir plus
Metamaterial-based absorbers play a significant role in applications ranging from energy harvesting and thermal emitters to sensors and imaging devices. The middle dielectric layer of conventional metamaterial absorbers has always been solid. Researchers could not detect the near field ... En savoir plus
